Application filed October 9, 1905. Serial No. 282,031.

To all whom it may concern:

Be it known that I, WILLIAM N. ORIsP, a citizen of .the United States,residing at Brooklyn Station, Baltimore, in the State of Maryland, haveinvented certain new and useful Improvements in Trace-Fasteners; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in devices for fastening traces towhiffletrees; and it consists in the novel construction, combination,and arrangement of parts hereinafter described and claimed.

The object of the invention is to improve and simplify the constructionand operation of devices of this character, and thereby render the samemore durable, less expensive, and at the same time more convenient'andreliable.

is a transverse sectional view taken on the line 3 3 in Fig. 2, and Fig.4 is a perspective view of the locking-button.

Referring to the drawings by numerals and letters, 1 denotes my improvedtrace-fastener, which consists of a main piece or body 2, alocking-button 4, a pin 3, and a coiled spring 5. The body 2 is tubularin form and has at one end a head 6, adapted to enter the opening or eyeof a trace, and at its opposite end areduced shank 7, adapted to besecured in the end of a whifiietree. The head 2 and shank 7 areseparated by an anular flange 8, upon the inner face of which and aroundthe same is formed an annular boss or enlargement 9. The bore in thetubular body 2 extends through the head 2 and partially through theshank 7, as clearly shown in Fig. 2 of the drawings. In the boss 9 isformed a transverse slot 10, which extends through approximatelyone-fourth of the same and has at one of its ends a recess or socket 11,as clearlyshown in Fig. 3.

The shank 7 may be secured in the end of the whifiietree Win any desiredmanner; but I preferably secure it by a rivet or cross-pin R, which ispassed through an opening 12 formed .in the shank and 'alining openingsformed in the end of the whiffietree and in its usual metal ferrule orcap F, as shown In Fig. 2. I

The locking-button 4 consists of a cylindrical stem 13 of slightly lessdiameter than that of the bore in the body 2, in which it is adapted toslide, and a transverse head or button proper, 14, which has its endsformed with inwardly-projecting portions 15, adapted to guard the outerend of the head 2 and prevent the trace from getting between the latterand the transverse head 14. The pro jections 15 are of slightly greaterdepth than the length of the recess or socket 11. The pin 3 has aslightly-tapered inner end, which is driven into a transverse openingformed n the stem 13, so that the locking-button wlll be retained in thebody 2. In assembling the parts the spring 5 is first inserted 1n thebore of the body 1, and the stem 13 is then placed in said bore. The pin3 is then driven through the slot 11 and into the opening in the stem13.

The construction, operation, and advantages of the invention will bereadily understood. It will be seen that when the device is mounted inthe end of a whiflietree, so that the recess or socket 11 is uppermostand vertically disposed, the transverse head or button 14 will bedisposed vertically when said pin 3 is seated in the socket or recess l1, as shown in Fig. 2. When the parts are In this position, it will beimpossible to turn the button 14 without first pushing it inwardly todisengage the pin 3 from the recess 11. When this is done, the buttonmay be given a guarter-turn to place it in a horizontal position, sothat a trace may be readily applied to or removed from the head 2 of thebody portion 1. The pin 3 turning in the slot 10 will limit the movementof the locking-button, as Wlll be readily understood. As soon as thebutton is again turned to its vertical position the coiled spring 5 willforce it outwardly and cause the pin 3 to seat in the recess or socket 11, and thereby lock the button against being casually or accidentallyturned. When the button is in its vertical position, it will beimpossible for the trace to turn the button to a horizontal position,since the button must be first moved inwardly to disengage the pin 3from the recess or socket 11. The trace being engaged with the head 2 ofthe body, which latter is securely fastened in the end of thewhiflietree, there will be no strain whatever upon the locking-butt.on,and hence no danger of the device breaking.

The parts may be made and finished in any desired manner, and owing totheir simplicity they may be quickly assembled at a comparatively smallcost. Owing to the fact that the spring, the pin, and the slot areentirely inclosed, they are well guarded and are not liable to becomebroken or to get out of working order.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A trace-fastener for whjfiietrees comprising a tubular body having atone end a trace-receiving head and at its opposite end afastening-shank, an annular flange at the inner end of saidtrace-receiving head, a boss upon the inner face of said flange andformed With a transverse slot having a recess or socket at one end, alocking-button consisting of a stem slidable in the bore of said body,and a transverse head upon the outer end of said stem, means forpreventing the trace from entering between said transverse head and theend of said trace-receiving head, a spring in the bore of said body forprojecting said stem, and a pin carried by said stem and coacting withthe slot and recess in said boss, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WILLIAM N. CRISP.
